How to control the placement of jobs

Myrinet v/s infiniband nodes

To control the placement of your job on the Myrinet (older)
or Infiniband (newer) part of the cluster,
you can specify the interconnect=mx or interconnect=fdr option in your
resource limits specification.

Controlling the placement of resource chunks

When requesting multiple chunks of hardware,
you may force each chunk to be on a different node
or on the same node, using place=scatter or place=pack:

-l select=2:ncpus=2:mem=15gb,walltime=00:20:00,place=scatter # force each chunk to be on a different node
-l select=2:ncpus=2:mem=15gb,walltime=00:20:00,place=pack # force each chunk to be on the same node
